Simplify: ((12x^-3)/(y^4))*(((y^-2x^2)^-1)/(15x^-2))

jhonyy9 (jhonyy9):

i like please you cooperate ok ?

jhonyy9 (jhonyy9):

a^(-1) = ?

OpenStudy (b77w):

1/a

jhonyy9 (jhonyy9):

12x^-3 = ? we solve it step by step

OpenStudy (b77w):

1/(12x^3)

jhonyy9 (jhonyy9):

no there just x has exponent of -3 or not ?

OpenStudy (b77w):

ok so 12/x^3

jhonyy9 (jhonyy9):

so than the first fraction will be ,how ?

jhonyy9 (jhonyy9):

inclusive with y

OpenStudy (b77w):

can you wait a moment?

jhonyy9 (jhonyy9):

ok

OpenStudy (b77w):

the first fraction is 1/12x^3y^4, yes?

jhonyy9 (jhonyy9):

not

OpenStudy (b77w):

What is it?

jhonyy9 (jhonyy9):

check your above answer for 12x^-3 when you have said that just x has an exponent of -3

OpenStudy (b77w):

12/x^3/x64

jhonyy9 (jhonyy9):

how you have got this x64 ?

OpenStudy (b77w):

i mean x^4

jhonyy9 (jhonyy9):

but there i not see x^4

OpenStudy (b77w):

i mean y^4

jhonyy9 (jhonyy9):

attention please because not is indifferent ok ?

jhonyy9 (jhonyy9):

so how will be the first fraction right ?
